◎Please see my profile. New, unused side fins. This is the perfect model for single stabilizer side fins. With a flat foil, it's an all-around model that combines high drive and versatility. Material: Fiberglass Height: Approximately 94mm Base: Approximately 89mm Deep fin box height The included soft case is slightly deteriorated. Consider it a bonus. ◎There are two types of Future Fin box heights: a deep one with an "f" mark on the box and a shallow one with an "x" mark. We cannot accept returns, exchanges, or complaints due to incorrect fin box height. Please check your board before purchasing. Thank you for your understanding. If the fins are difficult to attach or detach, please adjust them by sanding, etc. #Longboard #Midlength #Shortboard #Funboard #Simmons
